Fruit trees are especially vulnerable during the winter, and it’s necessary to protect them from the extreme weather that could harm them and lower the quality and quantity of fruit they produce the following year.
Every year, fruit trees become dormant and survive low temperatures in winter through acclimation. During acclimation, plants progressively develop greater cold tolerance.
Acclimation occurs from late summer through early winter and is triggered by shortening day lengths and decreasing temperatures.
After acclimation, fruit trees typically reach their greatest degree of cold hardiness in mild winter. Then, as days lengthen and temperatures warm during late winter and spring, fruit trees deacclimate. During deacclimation, plants lose their cold tolerance and prepare for active growth again.
Some winter injury occurs when mild-winter low temperatures are extreme. But winter injury can also be caused by sudden large temperature changes during the acclimation and deacclimation periods.
Factors that delay normal acclimation in autumn (e.g., excessive fertilizing or heavy pruning in late summer or early fall and the presence of bright light that mimic long day lengths) also make plants more susceptible to winter injury.
The following information will help keep your fruit trees healthy and fruitful all winter.
Protection from Animal Damage
Fruit trees frequently draw many animals, including deer and rabbits, who view them as a tasty food source. Use physical barriers like mesh fences or chicken wire around the tree trunk to shield your trees from animal harm.
To prevent animals from tunneling under the fencing, ensure it is at least six feet tall and buried six inches into the ground. Another choice is to put deer-repellent granules or sprays at the tree’s base to deter animals.
How to Protect Potted Fruit Trees in Winter
It’s crucial to take extra precautions to shield your potted fruit plants from the winter cold if you have any.
To avoid exposure to cold air, move the pots to a protected area, such as a garage or greenhouse, and place them away from windows.
For more insulation and to prevent the roots from freezing, you can wrap the pots with burlap or another material.
How to Insulate the Tree in Winter
Your fruit tree’s trunk can be shielded from winter damage and prevented from cracking due to temperature changes by being wrapped in burlap or a similar material.
Wrap the material around the tree’s trunk, securing it with twine or wire. A tree cover made expressly for winter protection might also be used if you reside in an area with a particularly harsh climate.
Insulation provided by snow cover or mulch can aid in the survival of fruit trees by buffering soil temperatures, decreasing the depth of the soil freezing, maintaining soil moisture during winter, and protecting plant parts from low air temperatures.
Mild winter temperatures and snowless winters often occur, and winter injuries can be severe during these mild winters.
Cold injury during the mild winter often results from lower soil temperature and soil moisture levels than from low air temperatures.
During these winters, the roots of fruit trees are often injured when snow cover and its insulating capacity are missing, and soil temperatures and soil moisture levels drop to points low enough to damage or kill roots.
How to Prune the Tree for Winter
Pruning is crucial to getting your fruit trees ready for the winter. It encourages healthy development and enhanced fruit production by removing dead, damaged, or diseased wood, which helps stop the spread of diseases and pests.
Before new growth starts, prune your fruit trees in late winter or early spring. Use clean, sharp trimming tools to reduce the possibility of causing damage to the tree.
There are more procedures you may take in addition to the ones mentioned above to ensure your fruit trees remain healthy during the winter.
These include ensuring the tree receives adequate water before the ground freezes and mulching the area surrounding the tree’s base, which aids in moisture retention and controls soil temperature.
Additionally, it’s crucial to watch for any signs of sickness or damage to the tree and intervene swiftly if necessary. A protective canopy can be placed over the tree, injured branches can be cut off, a fungicide can be used to stop the disease from spreading, etc.
Finally, selecting the best fruit tree variety for your region and environment is critical. Choosing the proper fruit tree species will ensure that your tree remains healthy and productive throughout the winter. Some fruit trees are more cold-hardy than others.
Finally, winterizing your fruit trees will help to ensure that they produce a robust yield during the upcoming growing season. You can ensure that your trees remain healthy and fruitful for many years by taking the time to safeguard them against winter harm.
Proper winter preparation is crucial whether you’re growing fruit trees in the ground or pots, and with a bit of work, you may enjoy a plentiful crop of fresh fruit every year.
